G'day, I have for a few months now been chasing a air in fuel issue after replacing injector pump. Son's ute gave up the ghost and we beleived ot to be injector pump so we swapped it out, amongst the fulthy intake manifold, stuffed lift pump, leaky turbe, air being sucked in through a faulty filter. Have since replaced all vacuum hoses and the fuel lines in under the bonnet the car starts, revs fine until the engine light pops on and drops to around 2000 revs. Apparently the code is still saying air in fuel not sure what else to look at other than fuel tank itself. Can't seem to rest the code. Any ideas anyone????
